Specific embodiment

The example that Fig. 1 shows the machine 100 for manufacturing artificial turf.Artificial turf is marked as 108.Machine 100 can be with Regard as artificial turf backing 102 and artificial turf fibres 104 as input.Subsequent fiber inserter 106 is by artificial turf Fiber 104 is inserted into artificial turf backing 102.Artificial turf 108 is considered as exiting fiber inserter 106.Dotted line frame 107 Be Fig. 2 shows a part, artificial turf 108 done more detailed display in Fig. 2.Subsequent artificial turf 108 runs through coating Colloid gluing 112 is spread out the bottom surface of artificial turf backing by device 110, the coater 110.Artificial turf fibres are from artificial turf Surface 116 is stretched out.In the example of explanation, roller is licked for applying colloid latex 112 to bottom surface 114 with rotating element 118. But this is not the unique method for applying colloid latex.Colloid emulsion coating can for example be assigned on the surface of bottom surface and then It is smooth with knife over roll method.Machine can also include colloid emulsion coating reservoir 111, store colloid emulsion coating and offer Colloid emulsion coating is to coater.In some instances, colloid emulsion coating reservoir 111 can be storage tank (not shown), With pipeline or the connection of pipe (not shown) colloid emulsion coating reservoir 111 is connected to coater 110.

The manufacture of artificial turf 108 is a kind of process based on net, and wherein artificial turf 108 passes through different websites.It will Colloid emulsion coating 112 is applied to after bottom surface 114, and artificial turf subsequently advances to 120 or less applicator.Such as the applicator 120 can be spray boom.Machine may include anti-foaming agent reservoir 121, can at least partly be filled with anti-foaming agent 122. In some instances, anti-foaming agent reservoir 121 can be storage tank, with pipeline 119 or pipe connection to store up anti-foaming agent Storage 121 is connected in applicator 120.

Applicator 120 is intended to indicate that any side for applying the colloid emulsion coating on a small amount of anti-foaming agent 122 to bottom surface 114 Method.

Artificial turf in frame 107 passes through from the lower section of applicator 120.So as it can be seen that anti-foaming agent 122 at least partly The exposed surface 124 of covering or wet colloid emulsion coating 112.Applicator is configured to the region 123 of wet exposed surface 124. In next step, artificial turf 108 passes through heater 126.Heater has entrance 125 and outlet 127.Applicator can be configured to make The region 123 of exposed surface that must be just wet is the distance 129 from the entrance 125 of heater 126.Command range 129 makes Artificial turf 108 enter heater 126 before, can control anti-foaming agent 122 exposed superficial residence how long.

Heater 126 takes off moisture from colloid emulsion coating 112, is converted into lisoloid coating 128.When artificial Turf 108 leaves heater 126, just completes manufacture.In some cases, artificial turf fibres 104 can leave heater It is modified after 126.However, what this was not the necessity for.

Heater 126 can be run in different ways.In this example, heater 126 has the first thermal control member Part and the second Thermal Control Element 132.First Thermal Control Element 130 generates the compressed air 134 with the first temperature range, and Second Thermal Control Element 132 generates the compressed air 136 with second temperature range.In this way, in the curing process, the temperature of bottom surface Degree can be different from the temperature of synthetic turf surfaces in this way.This can effectively take off moisture from colloid emulsion coating, Artificial turf fibres 104 are protected simultaneously.

Fig. 3 shows the flow chart of the operation of machine 100 shown in explanatory diagram 1.First in step 300, pedaline Hide fiber 104 is integrated in artificial turf backing 102 by fiber inserter 106 to form artificial turf 108.Next in step In rapid 302, colloid emulsion coating 112 is coated in the bottom surface 114 of artificial turf 108 with coater 110.Next in step In 304, the exposed surface 124 of colloid emulsion coating 112 is at least partly moistened or coated with applicator 120.Next in step In 306, at least bottom surface 114 of artificial turf 108 is heated so that colloid emulsion coating 112 is solidified into solid milk with heater 126 Gel coating 128.

Citric acid is used to carry out several experiments as anti-foaming agent.In experiment, before the drying, by 20% and 40% lemon Lemon acid solution is ejected into colloid latex compounds.In these tests, apply about 40-50g/m in these experiments².At this In a little experiments, blistering, rate of drying related with turbidity and relative humidity and tuft lock are checked.The colloid latex of inspection Closing object is styrene-butadiene latex.The result of blistering is qualitatively given in table 1.It can be seen that no lemon in table 1 Blistering quantity when sour is the largest.Blistering quantity with 20% solution is reduced.Blistering with 40% citric acid solution into One step is reduced.Table 1:

Citric acid	Blistering
		-	++
20% solution	+
		40% solution	+-

The display of table 2 checks experimental result when turbidity.It was shown according to 2 minutes, 3 minutes, 4 minutes, 5 minutes and 6 minutes Show result.As colloid emulsion coating becomes more dry, turbidity is reduced.Measuring turbidity is actually to determine colloid emulsion coating A kind of measurement of rate of drying.It can be seen that the concentration with citric acid increases, turbidity is also reduced.This shows that citric acid increases The rate of drying of colloid emulsion coating.This can help improve the speed of manufacture pile surface covering, therefore reduce into This.

Table 2:

Citric acid	2’	3’	4’	5’	6’
						-	+++	+++	+	+-	-
20%	+++	+++	+-	-	-
						40%	+++	+-	-	-	-

Table 3 shows the amount or concentration of the citric acid of the relative humidity and injection of the function as the time on the surface.Table 3 Spray citric acid on colloid emulsion coating as the result is shown and seem the reduction to relative humidity there is no significant impacts.But It is to carry out other test by spraying more citric acids on compound.The test is about application 200g/m²It is 40% molten Liquid.In this case, the relative humidity after 14 minutes only has 10%.It is in the experiment other from this as can be seen that acid anti- The rate of drying using certain influence relative humidity and therefore of foaming agent.This can be accordingly used in accelerating manufacturing process or add The manufacture of fast pile surface covering.

Table 3:

Time	Without anti-foaming agent	20% citric acid	40% citric acid
				14’	90%	80%	90%
16’	80%	70%	80%
				18’	70%	70%	70%
20’	30%	30%	30%
				22’	10%	10%	10%

Table 4 shows tuft lock/tufting bond strength of the pile surface covering of completion.This is with identical colloid latex What coating carried out, as previously mentioned, 20% citric acid of control group and 40% citric acid.Dry tuft lock experiment is in drying condition Under, weight needed for pulling out fiber cluster is covered from pile surface.After artificial turf has moistened 24 hours, wet tufting is carried out Locking.As can be seen from the table, it is sprayed on colloid emulsion coating before colloid emulsion coating is solidified into lisoloid coating Citric acid will not cause adverse effect to tuft lock.This existing method shape mixed with by anti-foaming agent and colloid emulsion coating At sharp contrast.This shows to spray the available excellent pile surface covering of anti-foaming agent on surface.

Table 4:

Citric acid	Dry tuft lock	Wet tuft lock is (for 24 hours r)
			-	5.0kg	5.2kg
20% solution	5.1kg	5.4kg
			40% solution	5.0kg	4.9kg

In conclusion these experiments show that spraying citric acid on colloid emulsion coating can be improved for blistering and muddiness The sensitivity of degree.Air can not impact relative humidity, unless applying greater concentrations of citric acid.It is applied in colloid latex Citric acid is sprayed on layer and seems that there is no adverse effects to tuft lock, in some cases, can change the painting of colloid latex The appearance of layer, because the residue of white fluffy can be deposited on the surface of colloid emulsion coating.But this has no effect on finally Product, because the bottom surface of pile surface covering is for example located on sightless ground.
